Our interest in this subject resides in the need to understand the new meanings of accounting and financial reporting considering that the importance of knowledge-based assets is increasing. Therefore, we have been interested in understanding some of the defining and essential aspects of a knowledge-based economy and we have tried to identify one of the Romanian industries, most marked by knowledge and intellectual capital and, in the end, we wanted to point out the main features of an accounting in knowledge-based economy. One of this paper’s objectives is to carry out a study at the macroeconomic level regarding the ICT Industry, a valuable element of knowledge-based Romanian economy, in the last half decade as well as of its constituent sectors: Telecommunications, Software and IT services and Hardware and electronics. The information contained in this study is based on the annual analyses of the Institute for Computer Technology, which, in its turn, is mainly based on processing the balance sheet data of the firms in the ICT industry in Romania and, also, information communicated by companies or provided by public institutions like NIS, NRB and NCA. The study is framed within the area of quantitative research, in a preponderantly inductive approach, using interpretative methods in order to understand the effects of economic conjunctures on the ICT industry, a knowledge-based industry, as a constituent element of a knowledge-based economy. We have noticed that the Telecommunication sector is the most unfavourable evolution during the entire length of time valuated, generating a negative influence. Even since 2007-2008, which corresponds to the economic boom, the growth recorded until then was attenuated. The slight increase of several indices (turnover and the production sold – returns form services, more exactly) and the slight reduction of the other indices part of the analysis (added value, export, number of forms and personnel) are the result of telephone market saturation, competition increase and the continuous tax reduction. The following years corresponding to the time of economic contraction negatively affected the evolution of the Telecommunication sector.
